Abstract

Optical nanoantennas are capable of localizing electromagnetic fields at the nanoscale and enhancing light-matter interactions such as fluorescence and Raman scattering. The multipole expansion of the light matter (e.g. dye molecules) interaction Hamiltonian is written by where p and m are electric and magnetic transition dipole moments of a molecule, respectively, and E and B are the electric and magnetic fields at the molecule position, respectively.
